# Thread: proof that the proof that .999_ = 1 is not a proof (version)

1. ## proof that the proof that .999_ = 1 is not a proof (version)

hello!

i think this should be posted here because, theoretically, this part of the forums is for the practical people, and they are the people most likely to appreciate this post.

please respond and let me know what you think - but try not to tell me anything that i already know (e.g. that i am useless and genius, charismatic and disrespectful, and theoretical and practical at the same time).

oddly enough, the only reason for you to respond is that there is no reason to respond.

2. Hello,

I think that this is a proof... As we're just using the fact that $+\infty=+\infty-1$... Don't you agree ?

Edit : ok, was talking about another version of the proof...

Why wouldn't we multiply an infinite expansion ? Thus your sentence 0.33......=1/3 is supposed to be false too...
D'you think you're revolutionnating mathematics ?

I can't see your attachment, but this topic has already been discussed (and consequently locked)

http://www.mathhelpforum.com/math-he...1-999-1-a.html

edit: Okay, you fixed the attachment

edit2: Also, the proof for .999=1 that you argued against is not the proof that mathematicians use.

edit3: Don't be too discouraged, though. I believe math is the only objective truth which exists, but I am still wary of mathematicians :P Skepticism is healthy.

5. Thread like this are banned. No attacking of math on MHF. Especially when it is coming from unexperience posters who think they know math.
